While reading lugnet recently, I stumbled upon an extremely interesting little robot. It’s creator says it best:

While waiting for the NXT system to come out, I decided to try my luck at making tiny robots… Often, when working, I would drop a SMT and have to take a magnifying glass to find it as it would get lost in the bits of filings, etc that were around the work area…

Believe it or not, this little guy is a sumo robot. When he senses he’s found, he runs full speed for the edge of the rink!
